- Toull whom it mag comm: I

Be it known that I, Anna s R. -PBIB[L, a

' citizen ofthe United States of Americafle- I purpose of equalizing the pressure in the siding at Detroitpin the countyof Vayne and State of Michigan, have'invented certain new and useful Improvements inLu: bricators, of whichthe following is a speciacco-mpanyingdrawings. a

This invention relates to a gravity-feed lubricato'r more specifically designed for lubricating the cylinderof explosive engines. In the construction of such lubricators it is necessary to provide a check valve in the fication, reference being had therein to-the outlet from the sight chamber and to end a ball valve is usually placed in the 'd s' charge outlet from the sight chamber to check the inrush, of the gases into said chamber while the explosion is taking place. As the gases at the time of the explosion are under very high pressure the small portion thereof which is permitted to pass around the ball valve into the sight chamber for the lubricator not only interferes with the formation of ,the drop but the fine sooty particles of carbon and smoke accompanying wall of the glass tube of the sight chamber and makes observation impossible.

It is the object of this invention to provide a construction which overcomes the trouble arising from the above mentioned cause and the invention consists to this end in the novel construction and arrangement of a ball-valve all as hereinafter described andshown in the accompanying drawings, in which- 7 Figure 1 is a vertical central section of a liibricator embodying my invention in its preferred form ;-Fig. 2 is a part of thedischarge arm thereof on an enlargedscale;

Fig. 3 is a horizontal section on line 3-3 of Fig. 2; and Fig. 1 is a horizontal section on line 1-4 of l ig. 2.

Referring to the drawings, 1 is a shell forming in connection with the heads 2 and 3 the oilveup, the shell being clamped between the heads by means of a vertical hollow post 4 integrally eastwith the bottom head and passing tirough an aperture in 'the top head, the projecting end being screw-threaded and provided with a clamp-: ing nut 5. The top of the hollow post-bears a notched screw cap 6 held against accidental the exploded charge in time coats the innen Within the hollow post is a valvesten1 8 terminating at its lower end in a tapering valve 9 and bearing at 'its upperend the snap handle 10 pivoted thereto whoseflat servesfto operate the stem 8 vertically to open or close the valve, a coil spring 11 being interposed between the cap 6 and a shoulder 12'forn1ed on the valve stem. The lowerhead -is formed with a valve seat for the valve 9 and with a discharge nipple 13 into the sight chamber below and communi-fi eating with the interior of the cup through the bottom of which is conically depressed and provided with a final outlet 20. The. "$01) of this chamber is formed by a screw plug 21 which is provided with a nipple 24- nearthe final outlet and inclosing the usual ballyalve' 25. The sight chamber isprovided with an outlet 23 through this nipple outlet and a seat 27 formed on the final outstructing the final outlet the latter is given a polygonal cross section,- the seat- 27 being formed within the area of the cross section as shown in Figs. 3 and 4. I g; The ball'valve when seated upon the final outlet prevents the oil from feeding freely jects into the lower end of the nipple and causes the formation of an oil seal between the same which while it doesnot interfere with. the proper operation of the device makes the ball valve very sensitive so that even at the slightest inrush of burnt gases into the chamber 19 the ball will quickly seat itself in the'nipple against the seat- 26 with the oil sealremainingpractically untened lower end rests upon the cap 6' and projecting into the expansion chamber to I v turning by a leaf spring 7 fastened in posi-l tion upon the post by the clamping nut 5. r

apertures M in the post. The sight cham- "it is .formed with an expansion chamber 19 in which the ball valve is guided in its movement between a seat 26 formed in this let 20. To prevent the ball from wholly obinto-the chamber 19 since its upper half proa ball valve in the expansion chamber movable between the two outlets, each outlet provided with a seat for the ball valve and 5 a nipple depending from the bottom of the sight chamber around the outlet therefrom into the expansion chamber and adapted to form in connection with the ball valve an oil seal between the two chambers.

In testimony whereof I atlix my signature in presence of two Witnesses.

broken. Any diffusion or inrush of burnt gases with the accompanying smoke particles into the sight chamber is thus prevented.

hile l have described my lubricator' witlrsole reference to its applicationfori explosive engines, it is quite obvious that it may be equally used in connection with air compressors or the like.

That I claim as my invention is In an explosion engine lubricator, a discharge arm having a sight chamber provided with an outlet at the bottom and with an expansion chamber below the sightchamber, having a final outlet at its bottom, 5
